I have submitted a patch to this mailing list that should fix these 
issues back in january, but the patch has not been commited to cvs 
unfortunately.

I have attached a patch against the current cvs checkout.

The patch modifies SConstruct such that blender is linked against the 
Python Framework that is shipped with OS X 10.3.2. Additionally blender 
is also linked against the 'objc' library, this seems to be required.

The patch assumes, that libjpeg and libpng are installed with fink in 
/sw. I think it would be even  better so include a precompiled version 
of libjpeg and libpng, such that blender can be built on OS X right out 
of the box, without any additional installation.

Also addressed by the patch. It makes sense to use 
../lib/darwin-6.1-powerpc as the path for precompiled libs, since this 
is the path where the libraries are located per default if they are 
checked out from cvs.

Best regards,
